Event-Driven Computing

In today’s cyberphysical systems streams of heterogeneous events from different domains and their associated data are continuously produced by sensors and embedded systems and provide real time information on many operational entities. Typical low-level events are the RFID tag readings detected at a warehouse gate, the GPS coordinates of a truck, or the readings of a temperature sensor in a container with food or pharmaceutical goods. These simple, low-level events can be combined and more abstract and application relevant events can be derived from them. For example, knowing the GPS position of a truck and the traffic conditions ahead, we can derive a complex event that tells us that the truck will arrive two hours late at its destination.
